IPC: H04L7/08
Filed: 1978-12-12
Abstract: PURPOSE: To prevent the large-scale transmission error and the like by detecting the erroneous synchronous state to carry out the assured synchronous recovery through preparation of both the search and check modes in the digital VTR.  
     CONSTITUTION: The bit pattern identical to the synchronous pattern of each block is detected from data signals SD which are divided into several blocks. Then signal SI is generated 15, and the search mode is set 16 in response to signal PG which is generated in synchronization with the initial of each track. And signal SI is detected to give the head leading of signal SD. Then each block of signal SD is counted 22, and thus block synchronous signals SYNC are generated in sequence and in correspondence to signals SI at the final bit of each block. In this case, if signal SI is obtained when the contents of counter 22 is under the fixed state, check mode setting means 31 leads out signal SI in the form of signal SYNC to give the renewal to the contents of counter 22.

Abstract: PURPOSE:To simplify the constitution of a picture recorder and to form a small- sized and compact device by arranging a cleaning means for removing powdery substances left on the surface of the image carrier after transfer on a position lower than a horizontal line passing the axial center of the image carrier. CONSTITUTION:The cleaning device 20 is arranged on a comparatively low position around a rotary drum 4 and an angle theta formed by a straight line obtained by connecting a point A where the edge part of a blade 20a is contacted with a photosensitive substance 4a to the center C of the rotary drum 4 and a perpendicular line from the center C is set up to 90 deg. or less when the drum is turned in the clockwise direction. Consequently, toner scraped off from the surface of the photosensitive substance 4a is dropped as it is and stayed in a cleaning box 20c, so that it is unnecessary to prepare a toner receiving plate or a receiving roller. The toner staying state in the box 20c is improved in accordance with the reduction of the angle theta in the positive range, and e.g. even when the angle is 30 deg. or less, a preferable result can be obtained. The angle theta is also available even if it is a negative value, and in case of a negative angle, theta>-90 deg. is preferable.
